Subject: [PATCH] libstdc++-v3/testsuite/.../year_month_day/3.cc, 4.cc: Cut
down for simulators
These two long-running tests happened to fail for me when
run in parallel (nprocs - 1) compared to a serial run, for
target mmix on my laptop. The runtime is 3m40s for 3.cc
before this change, and 0.9s afterwards.
* testsuite/std/time/year_month_day/3.cc (test01): Add ifdeffery to
limit the tested dates. For simulators, pass start and end dates
limiting the tested range to 100000 days, centered on days (0).
* testsuite/std/time/year_month_day/4.cc: Ditto.
